ADJUSTING DEVICE FOR HAT-FRAME MACHINES.

Specification of Letters Patent.

Patented July 30, 190'7.

Application filed April 3,1905. erial No. 253,396.

To all whom it may concern:

Be it known that 1, Jamie F. BROWN, a citizen of the United States, residing at the city of Chicago, State of Illinois, have invented a certain new and useful Adjusting Device for Hat-Frame Machines, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which-it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates more particularly to a device for determining the position of the hat frame supporting members of machines for forming hat frames of bent wire, such as that shown and described in U. S. Letters Patent No. 775,175, granted November 15th, 1904 to Winthrop M. Jameson, for device for forming hat frames, and has for its object to provide a cheap and simple means whereby the upper or hooked ends of the arms, about which the wires forming the hat frames are to be bent, may be much more quickly and easily placed in a predetermined position than by the means now in use.

So far as I am aware, these machines are at present set by placing a hat frame already made above them and adjusting the hooked ends of the upright members by placing the hooks thereof in proper position on the wires of the frame. During this process the frame must be supported with the hands and it is difficult to maintain the same constantly in proper position and at the same time manipulate the hooked members in the act of adjusting and fastening them. It thus results that this adjustment frequently cannot be made by those who are employed to make the hat frames after the machine has been once adjusted, and that the process of adjustment is a long and tedious one and must sometimes be repeated before a proper adjustment of the machine is obtained. As the adjustment must be frequently changed when new or different shapes are to be made upon the machine, a considerable amount of time and labor is expended in perfecting it. This loss 'I prevent by the use of the device hereinafter described.

In the drawings in which like characters of reference refer to similar parts in the different views, Figure 1 is a central vertical sectional view of a machine to which my adjusting device is applied, Fig. 2 is an enlarged detail view of one of the arms of the machine upon which my adjusting device has been fastened, Fig. 3 is a vertical sectional view of the support for the adjusting device, Fig. 4 is a sectional view of a detail, and Fig. 5 is a vertical central section at right angles to the section of Fig. 1.

10 indicates the support or standard of the machine and 11 the laterally extending arms thereof, which may be of any desired number. There are usually eight of them. Some of the arms may be hinged, as shown at 12, so that the hat frame, after being completed, may be readily removed from the machine.

13 are laterally extending guides in which fastening devices consisting of bolts 14 and nuts 15 are adjustably mounted. Upon these fastening devices are also mounted members 16 provided at one end with hooks 17 and at the other with guide-ways 18, through which guide-ways the bolts 14 pass. One of the members, 16, on each arm 11 is not provided with a guide-way, but is simply pivotally mounted on the bolt 14, as best shown in Fig. 3. These parts are all of old and well known construction and are substantially shown and described in the patent to Jameson above referred to, and are, therefore, not more fully described here.

Each of the arms 11 may be provided with a separate device for determining the position of its members 16 and 16 so that the positions of such members may be varied at will on the different arms to form a hat frame of irregular outline, when it is desired to do so. When the sides of a hat to be made are symmetrical a single adjusting device may be used for more than one arm 11, as hereinafter described.

20 indicates a board of wood, or other suitable material, cut away at its lower edge to [it over the guideway 13, the cut away portion thus acting to determine the lateral position of the board 20 with relation to the center of the machine.

21 indicates a clamping bolt which passes through a vertical slot 22 in the board 20, and also passes through a perforation in the upper end of a support 23 and is provided at one end with a thumb-nut 24.

25 are pins which may be in the form of ordinary nails driven at suitable points into the board 20 to form a pattern by which the machine is adjusted. The hooks 17 at the upper ends of the members 16 and 16 are adapted to engage with the pins 25, as shown in the drawings, to determine the position of said hooks, and, consequently, the shape of the hat frame to be made thereon.

The support 23 is provided with an offset 26, which, as shown in Fig. 3, enables the operator to easily adjust the bolts 14, which form the fastening devices for the hooked members 16 and 16. A base 27 is provided with a suitably placed forked member 28 fastened thereto by means of screws 29, and having its upward extension perforated to receive the bolt 30, which also passes through a perforation in the lower end of the support 23.

31 is the thumb-nut for fastening the support 23 in any desired position. The support or standard 10 is provided with a lug 32 set into the base 27. This enables the standard 10 to be rotated upon said base.

I may determine the position which the pins 25 shall occupy on the boards 20 by first completely adjusting the machine in the way already known in the art that is, by means of a hat frame supported by hand immediately above the machine to determine the position of the hook 17. When, by means of this frame the members 16 and 16 have been adjusted to their proper positions for duplicating said frame, I then place the boards 20 in position on the support 23, as shown in Figs. 1 and 5. This enables me to determine exactly where the pins 25 should be driven into the boards to reset the machine to duplicate the frame it is at the time adj usted to make. If it is desired afterwards to change the adjustment of the machine to make a frame of different shape, the machine may be readily returned at any time to its original adjustment by use of the boards 20 by simply placing said boards in turn upon the support 23 in connection with the various arms of the machine and adjusting the members 16 and 16 to their proper positions with the pins 25 in the hook 17. The support 23 may bemoved on its pivot from between the arms 11 to permit the rotation of the standard 10 to bring the proper arm in position to cooperate with its adjusting board carried on the support 23.

In Fig. l I have shown the parts in such position that the two arms there shown may be considered as being those arms of the machine which form and support the front and rear of the hat, and it is evident from an inspection thereof that as these two portions of the hat are not shaped alike, the members 16 and 16 on the right hand arm 11 will require a different adjustment from those on the left hand arm 11, and that therefore it may be necessaryto have a separate adjusting board for each of said arms, as indicated in full and dotted lines at the two sides of the figure. the case.

Referring to Fig. 5, if we suppose that the sides of the hat are symmetrical in shape, it is evident that the two arms 11 whiclrsupport and form the sides of the hat, may have the same adjustment and that the members 16 and l6 of both arms may be adjusted by a single adjusting board by bringing one arm after the other into position adjacent to the support 23. Thus it is often possible to have a fewer number of adjusting boards than there are arms on the machine when it is desired to make a frame of given shape.

It will be seen that by the use of my device the positions of the adjustable members 16 and 16 are positively determined by a device firmly supported adjacent to them and independently of them, thus avoiding the use of a pattern frame for returning the machine to any position in which it has been previously set. Such pattern frames'are apt to become bent in use and make it very troublesome to place the machine exactly in the desired adjustment.

Although I have herein shown and described tw independent and separate supports, one'for the members on which the hat frame is to be formed and one for the adjusting means by which said members may be placed in a predetermined position, this part of my Such, however, is not always 1 machine, as well as others, may be varied without departing from the substance of the invention, the chief object of my invention being to provide a pattern for predetermining the position of the adjustable members which will not depend upon said members for its support during the adjusting operation, but will leave said members free for manipulation by the operator, and will at the same time render it unnecessary to occupy the hands of the operator in supporting the adjusting means orpattern, as is the case wherea sample hat frame is employed for this purpose. Such changes in form are intended to be covered by the claims below.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is
